走向脑启发计算
Towards brain-inspired computing
摘要：
我们目前的介绍性考虑和分析计算应用程序的基础上，最近推出的确定性逻辑方案与随机尖峰（脉冲）列车[物理。A 373（2009）2338-2342]。此外，在考虑这些问题时，“为什么是随机的？为什么是脉冲？“，我们表明，基于随机脉冲的方案提供了实现多值确定性逻辑的优势。脉冲串由称为正交器的元件实现。我们讨论两种不同类型的正交，并行（基于交叉）和串行（基于解复用器）正交。最后一种可能会慢一些，但它使时序逻辑设计变得简单。我们建议通过使用芯片中可用的不相关高斯电噪声的过零事件来生成多维逻辑超空间[Physics Letters A 373（2009）1928-1934]。超空间中的尖峰序列是不重叠的，被称为神经比特。为了证明这个想法，我们分别使用2个高斯噪声作为神经比特的源来生成3维超空间基。在这种情况下，不同超空间基础元素的检测可能具有极大不同的延迟。我们表明，它是可能的，以提供一个相同的速度为所有的超空间基地的元素使用相关的噪声源，并证明这2神经比特的情况。本文的主要影响是证明，使用这种神经位的逻辑设计方法可以产生一个快速，低功耗的处理和环境变化容忍的计算机电路设计方法。它还可以实现多值逻辑，通过允许在单根导线上传输多个神经位来显着增加计算机电路的复杂性。
英文摘要：
We present introductory considerations and analysis toward computing applications based on the recently introduced deterministic logic scheme with random spike (pulse) trains [Phys. Lett. A 373 (2009) 2338-2342]. Also, in considering the questions, "Why random?" and "Why pulses?", we show that the random pulse based scheme provides the advantages of realizing multivalued deterministic logic. Pulse trains are realized by an element called orthogonator. We discuss two different types of orthogonators, parallel (intersection-based) and serial (demultiplexer-based) orthogonators. The last one can be slower but it makes sequential logic design straightforward. We propose generating a multidimensional logic hyperspace [Physics Letters A 373 (2009) 1928-1934] by using the zero-crossing events of uncorrelated Gaussian electrical noises available in the chips. The spike trains in the hyperspace are non-overlapping, and are referred to as neuro-bits. To demonstrate this idea, we generate 3-dimensional hyperspace bases using 2 Gaussian noises as sources for neuro-bits, respectively. In such a scenario, the detection of different hyperspace basis elements may have vastly differing delays. We show that it is possible to provide an identical speed for all the hyperspace bases elements using correlated noise sources, and demonstrate this for the 2 neuro-bits situations. The key impact of this paper is to demonstrate that a logic design approach using such neuro-bits can yield a fast, low power processing and environmental variation tolerant means of designing computer circuitry. It also enables the realization of multi-valued logic, significantly increasing the complexity of computer circuits by allowing several neuro-bits to be transmitted on a single wire.
